I have a 2001 Silverado, it blows cold air, however the 1 & 2 settings are very very low, and 3 and 4 are very similar, and 5 I would like it to blow out a lot more air. Would my problem be my fan? I feel like it should be blowing out more air than it is. I have changed the filter before several times, yet still no significant change.

@geddingtonfire It could be the blower motor resistor. You may also want to remove the blower motor to see if anything has ended up in the cage that could be slowing it down. Such as leaves or dirt. Hope this helps you out.

Great video. I have a 98 Chrysler concorde. The AC doesnt work in summer. But for winter the heating works great. I actually have to change actuator for heating to work again. Any guess on what is causing the AC not work. The air out of the fan is very hot in summer.

Thanks in advance!!!

@crosstalk125 You may want to have someone check it for you to see if the refrigerant level is up and not empty. It may need to be charged.

@bjbenbj We haven't done a video on a 98 Tahoe blower motor, but the procedure may be very close.

@reposado28 It could either be the blower motor resistor or maybe even a loose connection or wire somewhere. I would check to see if there's power to the blower motor and the resistor with a test light.

i have a 1997 chevy blazer, and it used to blow good then the air started to go on and off while the vehicle was moving and now it doesnt blow at all, how does it sound like to you?

@bjbenbj It could be the blower motor resistor, or possibly the switch.
